GEARING FOR AUTOBINDERS.

Specification of Letters Patent. Patented Sept, 19, 1916,

Application filed December 26, 1911. Serial No. 667,724.

' To all whom t ymay concern Be it known that I, VACLAV M. HoRACnK, acitizen of the United States, and a resident of Tabor, in the county ofBonhomme and State of South Dakota, have invented certain new and usefulImprovements in Gearing for Autobinders, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to certain new and useful improvements of farmimplements propelled b y means of a motor and comprises a tractorcarrying a self binder, the motor, however, being detachably secured tothe binder.

The primary object of my invention is to provide an auto self binder,the operating mechanism of which is driven by the power of the tractor'.

Another object is to provide an autobinder so constructed that theoperator may control the motor and the tractor, while controlling themechanisms of the self binder.

A still further object is to provide a self binderwith a power drivenpulley to which a belt may be connected -to drive'certain auxiliarymachinery, such as a corn sheller, elevator and the like.

Another object of my invention is to provide a self binder having apropelling mechanism provided with -a steering. wheel, and a footoperated mechanism controlling the grain wheel of the binder.

A still further object is to provide an auto-binder with atransportation truck detachably secured to the machine and ar ranged tobe driven by the driving motor.

lVith these and other objects in view the present invention consists inthe combination and arrangement of parts as will be hereinafter morefully described and finally pointed out in the appended claims, it beingfurther understood that changes in the specific structure shown anddescribed may be made within the scope of the claims without departingfrom the spirit of the invention.

In the accompanying drawings forming a part of'this specification and inwhich like characters of reference indicate similar parts in the severalviews: Figure 1 shows a top view of an auto-binder embodying myinvention, with the elevator detached. Fig.

2 shows a rear end view with parts broken away, showing the elevator andpart of the chute. Fig. 3 shows an enlarged detached same can be usedwhile the binder is out of service. y

In the drawings A designates al suitable reaper, B the elevator as shownin Fig. 2, and C the chute. The reaper and binder are of any approvedconstruction.

In the drawings the main frame 3 is shown as giving support'to the bullwheel 2, while secured to the outer end of the reaper A is the grainwheel l.

Extending from the carrying frame and detachably secured to the frameportion 52 shown in Fig. 1 is the tongue 4G which is secured by means ofthe brace 53 and this tongue 46 as shown in Fig. 5, at its forward end,carries the bearing head 54. Revoluloly held within this head 54 is thestem of the I caster fork 48 giving support to the caster wheel 55.Fixed to the stem of the fork 48 is the bevel gear 5G. The machine isguided by means of this caster wheel 55, though by means of the grainwheel 1, the machine can also be guided within certain limits, as willbe described more fully hereinafter.

Held to the transverse frame members a, is a platform 19 carrying themotor M.

This motor has the driving shaft c, which is operated by means of thestarting crank 45 as is usual in gasolene motor construction. The motorM drives the fly wheel 57 having the friction clutch 50, the movablemember 5S of which is actuated by means of the striding clutch arm 49,pivoted to the bracket G0 as shown in Fig. 1. Extending from this clutcharm 49 is the connecting rod 18, which is led to a clutch lever 17. Thislever is pivotally held to a suitably notched sectoi` 16 secured to themain frame as shown 1n Fig. 2. The movable member 58 is splined to themain driving shaft 0, and is brought into engagement with the frictionclutch 50,

when it is desired to rotate the driving shaft c. This driving shaft atits end is provided with the worm 22, working in connec` tion with theworm gear 21, this Worm gear being secured to the main shaft 32. Asshown in Fig. 2, this main shaft 32 is held within the bearing 2O and33, and at one end has secured to it the bevel pinion 31, meshing withthe clutch gear 9 shown in Fig. l. This gear' 9 is securely held to thedriven shaft l0, and is arranged for co-action with the clutch chaingear 43. The chain gear 43, as shown in Fig. 1, is operated by means ofthe controlling lever 38 which is connected to the notched bar 65, bymeans of an ordinary spring actuated detent in a manner insuring thelever 38 being adj ustably held.

ther parts of the harvester (not shown) may be operated by a chain 44which passes around the wheel 43. l

As shown in Fig. l the driven shaft 10 carries the bevel pinion 42meshing with the drive gear 4l secured to the shaft 68 of thetransmission gearing. In the drawings the housing surrounding thetransmission gearing is marked T, which transmission gearing iscontrolled by a lever 35, suitably fulcrumed upon the carrying frame andequipped with the usual sector-engaging detent, said lever being linkedas at 34 to a shifting lever of said transmission gearing, all asclearly disclosed in Fig. 2. This transmission gearing is adapted to bemanipulated by a lever 35 and link 34 in any suitable manner. Thistransmission gearing is carried upon suitable brackets extending fromthe carriage and at its end works within one of the members a. Thetransmission shaft 68', forms a continuation of the shaft 68, as shownin Fig. 1, and at its inner end carries the chain sprocket 40, andpassing over this sprocket is the chain 69 also passing over the chaingear 70 secured to the bull wheel 2.

From the foregoing description it will be noticed that driven shaft 1()is in gear connection with the main shaft 32, which in turn, is in wormgear connection with the driving shaft c.

At its forward end the shaft 10 carries the disk 70 to which is suitablysecured the pitman 11, driving the sickle.

As shown in Fig. 2 the main shaft 32 also carries the chain gear 72 overwhich passes the chain 73, at its upper end working over the chain gear74. This gear 74 is held upon a shaft 75, carried within the bearing 14,suitably secured to the elevator frame B and also connected to the framepost 5. l At its outer end this stub shaft 75, carries the drivingpulley 5 shown in Fig. 3 and working from this pulley 5 is the drivingbelt 6 which also passes over` the driven ratchet faced pulley 7 workingupon the rear shaft 12.

As shown in Fig. 2, the pulley 7 is provided with a grooved hub 25,having a ratchet face arranged for co-action with the ratchet collar 8',fixed to the rear shaft 12. To operate the shaft l2 it is necessary tobring the members S and 25 into contact.

This is accomplished by means of the lever 9', the lower forked end ofwhich is held within the groove of the hub 25. The lever 9 is held inadjustable position by means of a suitable detent engaging within thenotches of the sector 24.

As shown in Fig. 3, I employ a suitable foot lever 26 having a groovedshive 28 working in conjunction with the loose belt 6 passing over thepulleys 5 and 7. In tightening the belt 6 as shown in Fig. 3 the shafts75 and 12 are operatively connected.

In order to promptly turn the auto-binder at right angles the operatorthrows the main bull wheel out of gear and reverses the grain wheel 1.In order to reverse this grain wheel 1, I provide the rear shaft 12,adjacent to the drive belt pulley 7, with the internal gear 3 shown inenlarged detail in Fig. 4. This gear is loosely held upon the shaft 12,between the collar 30, and the bearing 23. In normal engagement with theinternal gear 3, is the spur pinion 2 held upon the pintle 80, thispintle being carried by an arm 23, while keyed to the shaft 12, meshingwith the spur pinion 2 is the spur wheel4. In order to reverse the shaft12, the operator merely throws the belt pulley lever 9 in the properdirection so that the ratchet faced pulley 7 will engage the y ratchetface 30 of the internal gear 3. Then in tightening the belt 6 the drivenbelt pulley 7 may be brought into engagement with said internal gear torotate the same.

As disclosed the foot lever 26 is held to an ear 81`, secured to asuitable part of the binder frame 27 as shown in Fig. 3, so that thegroove shive 28 may be thrown against the belt 6, to tighten the same asshown in Fig. 3. The foot lever 26 is placed in front of and below theseat 83 as shown in Fig.

2, this seat being held upon the post 7 The L seat 7, is held to a frameportion fixed to the upper end of the post 5.

Held within the bearing 47, shown in Fig. 5 and secured to the. forwardend of the tongue 46, is the steering shaft 29, at its end carrying thebevel pinion 84, in mesh with the gear 56. At its upper end the steeringshaft 29 is provided with the steering wheel 85, this wheel being heldin front of and proximal to the seat 83.

Harvesters as usually constructed are provided with a set of so calledtransport truck wheels which' are detachably secured to a suitable partof the binder. By means of these wheels the binder is drawn to and fromthe field. When the transport wheels are in use the tongue 46 isdetached and is secured to the end of the binder platform below thegrain wheel l. This construction permits the implement being carriedthrough comparatively narrow gates. In my invention, in order that thetransport wheels may be driven by the motor M, I provide the drivingshaft c with the chain sprocket 51. A suitable chain is made to passover this sprocket 51 and other suitable chain sprockets secured to thetransport truck wheels. These wheels can then be used as drive wheels indrawing the binder to and from the field. Vhen the transport truckwheels are removed the chain is removed from the sprocket 51. As thetransport wheels do not form a part of my invention they have not beenshown in the drawings.

In guiding the auto binder in a circular path, the machine is steered bymeans of the caster wheel 55, and the grain wheel 1.

From the foregoing it will be understood that the shaft 12 is controlledby means of the foot lever 26, through the intermedium of the belt 6 andthe'connected pulleys.

In removing the steering shaft and caster wheel the auto binder can atonce be drawn and operated by means of suitable draft animals.

The binder mechanism is operated by the motor. Under these conditionseven in the heaviest grain there will be no choking of the bindermechanism for the reason that where the stand of grain is particularlyheavy the auto binder is slowly advanced, while the operating mechanismis working at its maximum speed. This construction also eliminates anystalling of the auto-binder as is the case where the binders are drivenby the bull wheels, as when the machine is drawn by draft animals.

As the auto-binder is used but a very short time during each year, themotor M, is detachably secured to the platform so that the same may bedrawn forward off of its platform and be used in driving othermachinery.

The shaft 12 is held at its outer end within a bearing bracket 86, andat its projecting end has the chain sprocket 85. The grain wheel 1, hasa chain sprocket 87 and connecting this sprocket 85 and 87 is a chain13.

The shaft 68 is connected to a transmission of any approved constructionincluding two forward speeds, one reverse and one out of gear.

Having thus described my said invention, what I claim as new and desireto secure by United States Letters Patent is:

1. In a device of the character described in combination, a main shaft,a pinion at the end of said shaft, a driven shaft, a clutch gear on saiddriven shaft in mesh with said pinion, a clutch chain gear upon saiddriven shaft, means to operate said chain gear, a pinion secured to saidchain clutch gear and splined to said driven shaft, a transmissiongearing, a shaft extending from said transmission gearing, a bull wheel,and means to operatively connect said bull wheel to said transmissiongearing shaft.
